This species does not belong to Fox's group imperialis as indicated 

 by Melander but is a true Dasymutilla and is closely related to caneo 

 Blake. It is readily distinguished from the latter species by the 

 black appressed pubescence on the dorsum of the thorax. The speci- 

 mens vary in length from 4.5 to 10 mm. The postero-lateral tuber- 

 cles of the head are present in this species but more or less obscure.
